IEA HPP Annex 47: Heat Pumps in District Heating and Cooling Systems
A significant use of alternative heat sources with the help of district heating and cooling networks is a major challenge for a sustainable energy supply. In times of increasing shares of fluctuating producers such as PV and wind energy, the relevance of heat pumps increases. Within the framework of the IEA HPT Annex 47, potentials and barriers for the integration of heat pumps in DHC networks were analyzed.
IEA HPT Annex 61: Heat Pumps in Positive Energy Districts
IEA HPT Annex 61 evaluates the role of heat pumps (HP) in positive energy districts (PED). Efficiency potentials of the electric and thermal energy of districts that can be unlocked with the use of HPs are evaluated in order to reach a positive energy balance. This refers to both, upgrade of waste heat and simultaneous generation of different energy use in buildings (space heating, DHW, space cooling/dehumidification) and includes self-consumption of on-site renewable electricity generation.
IEA HPT Annex 48: Industrial Heat Pumps, Second Phase
Industrial heat pumps enable the use of waste heat and increase the energy efficiency of industrial processes. The aim of this project was to provide comprehensive information on the successful application of industrial heat pumps and thus contribute to the further dissemination of this technology.
IEA HPT Annex 60: Retrofitting Heat Pump Systems in Large Non-domestic Buildings
Lack of knowledge about retrofit options with heat pumps currently hinders the widespread use of the technology in non-residential buildings. In this project, easy-to-use, accessible recommendations for techno-economically optimised planning / design of heat pump applications in hospitals, shopping centres, industrial buildings, educational institutions, and museums will be developed and communicated to relevant target groups in the form of guidelines and training courses.
